Description: By jumping Yel/blu to Yel/blk,
you are turning on the main fuel injection. By
jumping Blk/yelto
Yel,
you are turning on the fuel pump. It doesn't
matter if the main
relay is
removed or not. Disconnect the fuel pump, Blk/yel
to Yel, when engine is not running.

Understanding:
Knowing the nature of the problem and
understanding how it works can protect your car
from accidental damages. Honda electronics are
known for it's reliability, but the new models
(92 and up) employ a different kind of igniter
that may be damaged if a positive current is
supplied to one of wrong inputs. Honda is designed for ground safe, meaning accidental grounding may not damage the computer electronics.
